IMPORTANT NOTICE
The Petite Trotte à Léon (PTL) is significantly more technically demanding than the majority of trail events, including the UTMB®. It requires expert knowledge and extensive experience in mountain environments. Key challenges include steep slopes, unstable terrain and very narrow trails. Sections with scree, snowfields and areas without defined paths. Potential risks influenced by weather conditions include: Rockfalls and river flooding and highly exposed and steep sections. The route is NOT MARKED and is often FAR FROM INHABITATED AREAS. Participants are 100% autonomous between checkpoints, refreshment points and partner shelters. To safely participate, entrants must : master navigation techniques with a GPS (mandatory) and be able to use a map, compass and altimeter. Work as a team, remaining close to one another at all times. Be prepared to handle harsh natural conditions.
INTRODUCTION
ORGANIZATION
The PTL® is organized by UTMB Group in collaboration with the Amis de l’UTMB association, and overseen by a Race Committee whose decisions are final.
ACCEPTATION OF THE RACE REGULATIONS AND ETHIC
UTMB® participation requires full, unconditional acceptance of the rules and the ethos of the event, as well as compliance with any instructions from the organizer.
OVERVIEW OF THE EVENT
The aim of the PTL® is to complete a given course within a given time. It is a non-competitive adventure and, as a result, does not include an official ranking.
The event is open to female, male, or mixed teams of 2 to 3 participants, with a maximum of 300 runners.
Teams must remain together. If a team of 3 loses a member, the remaining 2 may continue after ensuring their teammate has reached safety (at a checkpoint or refuge), and with approval from the Race HQ. For teams of 2, any withdrawal results in the team retiring.
The route is semi-autonomous with support provided by the organization at:
- Checkpoints: Open during designated time windows; free dormitories and meals are provided, along with access to drop bags. - Partner refuges: Open 24/7, offering free dormitories and meals (with a meal ticket**). Space in dormitories may be limited during peak times. - Services offered by non-partner refuges are at the participants expense with due respect for the refuge’s opening hours and other guests.
Outside assistance is strickly prohibited at any point on the course — including at checkpoints, partner refuges, village or road crossings — on pain of immediate disqualification.
Accompaniement by third parties is also prohibited at any point on the route
*Some partner refuges offer refreshments only. These details will be sent with the roadbook.
** Within the limit of the 4 meal tickets distributed.
CONDITIONS FOR PARTICIPATION AND REGISTRATION
ENTRY PROCESS
Entry requires submitting an application detailing each team member’s prior mountain experience, technical skills, and team motivation. The evaluation process may include a lottery if demand exceeds the 300-runner limit. If all the selected 3-person teams do not reach the limit of 300 runners, a draw will be made from among the 2-person teams. If all the selected 3-person teams exceed the limit of 300 runners, a draw will be made among the 3-person teams and no 2-person teams will be selected.
The PTL® is open to anyone born in 2005 or earlier (U23 to veteran categories), with or without a racing license.
To validate their entry, each runner must:
- Complete an online course focusing on risk awareness and best health practices in sport, which replaces the requirement for a medical certificate. It takes less than 5 minutes! (Following a change in French legislation a medical certificate is no longer required for HOKA UTMB Mont-Blanc 2025 races. This change is due to the introduction of the Parcours de Prévention Santé (PPS), a scheme set up to support athlete health.)
New registration validation process with PPS:
• Login: Visit the official PPS website three months before your race to start the online course.
• Follow the online awareness course: Complete the modules that will guide you through the essential risks, precautions and recommendations for running.
• PPS code: At the end of the course, you'll receive your PPS code, which you'll need to enter in your dashboard.
• Dashboard: At the end of the online course, copy the PPS number into your dashboard (Heading: File status) to complete your registration.
Make sure that your details (first name, last name and date of birth) match your Njuko registration.
- Complete all additional actions required for registration before August 15, 2025, (declaration, race bib collection, telephone number, etc.) using the online form available in the runner's area.
